litsea japonica/悪性腫瘍

Non-small cell lung carcinoma (NSCLC) is a major killer in cancer related human death. Its therapeutic intervention requires superior efficient molecule(s) as it often becomes resistant to present chemotherapy options. Here we report that vapor of volatile oil compounds obtained from Litsea cubeba

Litsea is considered as an evergreen genus distributed in tropical and subtropical Asia; this genus belongs to the large family of Lauraceae. In this study, the cell-death metabolism of biseugenol B was investigated. Nuclear condensation, cell permeability, mitochondrial membrane potential (MMP) and

The in vitro cytotoxic activity on human cancer cell lines of sixteen commercial EOs such as Aloysia triphylla , Boswellia carterii , Boswellia serrata , Cinnamomum zeylanicum , Cistus ladanifer , Citrus × aurantium , Citrus limon , Citrus sinensis , Cymbopogon citratus , Foeniculum vulgare ,

A new styrene dimer derivative has been isolated from the branch of Litsea greenmaniana by column chromatography over silica gel and Sephadex LH-20, as well as semi-preparative HPLC. Its structure was identified by spectroscopic data analysis (MS, UV, IR, 1D and 2D NMR) as

BACKGROUND Helicobacter pylori (HP) is a gramnegative bacterium and well recognized as being the primary etiological agent responsible for the development of gastritis, dyspepsia, peptic ulcer disease and gastric cancer. In developing countries, a high prevalence of HP infection is associated with

We examined the antiosteoarthritic effect of the n-hexane extract of Litsea japonica fruit flesh (LJF-HE) in a rat model of monosodium-iodoacetate- (MIA-) induced osteoarthritis. LJF-HE significantly reduced the difference in weight-bearing capabilities of the hind paws between healthy and

To investigated the activities of chloroform fractions at pH 7 of Litsea cubeba Lour. Fruits and heartwoods (CF-7F and CF-7H) in decrease expression of PI3KCA, Akt-1 and Akt-2 genes towards cervical cancer cell culture (HeLa) experiments in

Litsea cubeba is one of aromatic medicinal plant belonging to family Lauraceae. The roots, stems and fruits of L. cubeba have been widely applied as folk medicines in some districts in China for relieving rheumatism and cold, regulating Qi (meridian) to alleviate pain. Previous studies revealed that

Two novel flavonoids with chalcone skeleton, together with seven known flavonoids, were isolated from the stem barks of Litsea rubescens and Litsea pedunculata. The structures of the new compounds were elucidated on the basis of spectral methods including IR, UV, 1D and 2D NMR. The new chalcones

Nitric oxide (NO) produced by inducible nitric oxide synthase (iNOS) has played a crucial role in various pathophysiological processes including inflammation and carcinogenesis. Therefore, the inhibitors of NO synthesis or iNOS gene expression have been considered as potential anti-inflammatory and

The genus Litsea is predominant in tropical and subtropical regions of India, China, Taiwan, and Japan. The plant possesses medicinal properties and has been traditionally used for curing various gastro-intestinal ailments (e.g., diarrhea, stomachache, indigestion, and gastroenteritis) along

Oxaliplatin is widely used in the treatment of variety of cancers, including cancer of the testis and colorectum. Gap junctions (GJs) can amplify the cytotoxicity of antinoeoplastic drugs through the bystander effect in different cancer cells. In this study, we demonstrate that total flavonoids of

Five novel isoquinoline alkaloids (+)-N-(methoxylcarbonyl)-N-nordicentrin (1), (+)-N-(methoxylcarbonyl)-N-norpredicentrine (2), (+)-N-(methoxylcarbonyl)-N-norbulbodione (3), and (+)-N-(methoxylcarbonyl)-N-norisocorydione (4), and (+)-8-methoxyisolaurenine-N- oxide (5) were isolated, together with

The leaf and fruit essential oils of Litsea cubeba, extracted by hydrodistillation, were assessed for anticancer activities. A total of 53 and 50 compounds were identified, respectively from the leaf and fruit oils, and their yields were 13.9 +/- 0.09% and 4.0 +/- 0.03%, v/w, of the oven-dried

Litsea cubeba oil is an aromatic essential oil extracted from the fresh fruits of Litsea cubeba (Lour.) Pers. It is used as a flavor enhancer in foods, cosmetics, and cigarettes; as a raw material in the manufacture of citral, vitamins A, E, and K, ionone, methyl ionone, and perfumes; and as an
